The sum of the angle measures of any triangle is 180 degrees. Angle 2 is twice the measure of angle 1. Angle 3 is 15 degrees les
s than the measure of angle 2. What is the measure of each angle?

Answer:
Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63
Step-by-step explanation:
78/2 = 39
(Angle 2/2 = Angle 1)
78 - 15 = 63
(Angle 2 - 15 = Angle 3)
39 + 78 + 63 = 180
(Angle 1 + Angle 2 + Angle 3 = 180)
Answer:
39°, 78°, 63°
Step-by-step explanation:
let ∠ 1 = x, then
∠ 2 = 2x ( twice the measure of ∠ 1 )
∠ 3 = 2x - 15 ( 15° less than ∠ 2 )
Sum the 3 angles and equate to 180
x + 2x + 2x - 15 = 180, that is
5x - 15 = 180 ( add 15 to both sides )
5x = 195 ( divide both sides by 5 )
x = 39
Thus
∠ 1 = 39°
∠ 2 = 2 × 39° = 78°
∠ 3 = 78° - 15 = 63°

Hi! :)
5/100 = 0.056 sales tax
$12 + $26 + $125 = $163 total purchase without tax.
163 * 0.056 = 9.128 tax based on how much she bought.
$163 + 9.128 = $172.128 total amount she paid.
